Reacting to boos, Romney goes off-script

(CNN) – Mitt Romney was met with a round of boos Wednesday during his speech at the NAACP convention in Houston, after he voiced his goal to repeal "Obamacare."

"I'm going to eliminate every non-essential expensive program I can find. That includes Obamacare, and I'm going to work to reform and save," he said, before being interrupted by the unhappy crowd.

The presumptive GOP presidential nominee paused for 15 seconds, as he looked out over the crowd hissing and jeering.

Instead of moving on to his next point, Romney went off-script to back up his claim.

Romney mentioned, as the boos began to fade, a survey of 1,500 members of the Chamber of Commerce, in which three-quarters said President Barack Obama's health care plan made them "less likely to hire people."

"So I say again," Romney continued. "If our priority is jobs, and that's my priority, that's something I'd change and I'd replace with something that provides to people something they need in health care, which is lower costs, good quality, a capacity to deal with people who have pre-existing conditions and I'll put that in place."

He then went on to make his next point, as listed in his prepared remarks.

The candidate had a few more boos from those who took issue with some of his positions. However, Romney also received some applause lines, as well as a few bursts of organ music during the remainder of his speech.
